The 4C5 China Feed Industry Information Network focuses on feed-related information and serves the animal husbandry industry. The addition of organic arsenic in animal feed can help improve growth and enhance the color of the animals' coats. The Ministry of Agriculture denied the rumors about pigs dying from arsenic poisoning due to feed additives, but raised concerns about public misunderstanding. Some feed additives used to promote animal growth have been banned in certain countries due to their harmful effects on livestock and environmental pollution. Like many other chemicals, our understanding of organic arsenic has evolved over time. Today, food safety is a major concern for many Chinese people, and the fear surrounding feed additives, such as the "dead pig" rumors, reflects this widespread anxiety.
Pig Rumors The sight of thousands of dead pigs floating in the Huangpu River sparked nationwide speculation about the cause of their deaths. Although official sources repeatedly stated that the pigs were not diseased but had died naturally or from freezing, and that the water supply was unaffected, public skepticism remained high, with various theories still circulating. Among the most popular rumors was the claim that "pigs died from arsenic poisoning." It was said that organic arsenic added to pig feed could accelerate growth and make their fur appear redder and more attractive, which would increase their market value. However, long-term use could lead to arsenic accumulation in the pigs’ bodies, increasing mortality rates. This rumor gained traction during a period of heightened public sensitivity. The anti-corruption campaign reduced pork demand during the Spring Festival, leading to an oversupply of pigs. Some believed that these pigs, which had been fed arsenic, were left unprocessed and eventually died, contributing to the floating dead pigs. The combination of events fueled public fear, anger, and widespread sharing of the rumor. Scholars and experts later challenged the validity of these claims. For example, a post by Zhu Yiwei, an associate professor at China Agricultural University, explaining the science behind arsenic in feed, was met with backlash from some netizens who accused him of misleading the public. As the "arsenic pig" rumor spread rapidly, even government officials could not ignore it. On March 20, the Ministry of Agriculture issued a statement confirming that tests conducted by the Shanghai Veterinary Feed Testing Institute found no arsenic in tissue samples from 30 dead pigs retrieved from the river. This effectively debunked the rumor. Despite this, public interest in arsenic remained high. People began asking: Why is it added to feed? What are its benefits and risks?
containing Additives According to scientific knowledge, arsenic exists in both organic and inorganic forms. Elemental arsenic is relatively non-toxic, while inorganic arsenic is highly toxic. Studies show that trivalent arsenic is more dangerous than pentavalent arsenic. In modern societies, inorganic arsenic is commonly found in foods like grains, vegetables, and beverages. Seafood often contains higher levels of total arsenic, but mainly in organic form. For the general public, such technical terms can be confusing. However, the phrase “arsenic is arsenic†made the issue easier to grasp and remember. Some netizens questioned whether the substance was poisonous, where it came from, and how people could avoid it. In 2011, some media outlets reported that arsenic was detected in U.S. chickens. However, the story quickly faded from public memory. Many people forgot the term “Roxarsone,†a drug once widely used in poultry farming. Some reports even simplified the title to “Frozen Chicken,†making it easier for the public to understand. At that time, the FDA found that chickens treated with Roxarsone had higher levels of arsenic in their livers. However, the amount in meat was much lower and considered harmless. Pfizer, the company that produced the drug, voluntarily stopped selling it in the U.S. in 2011 and also suspended sales for pigs and turkeys. The FDA warned that if further research showed the drug to be carcinogenic, it would be removed from the market. Roxarsone had been used in the U.S. for decades. It was first approved for chicken feed in 1964 and later recognized as a necessary trace element for animals. By 1983, it was officially approved as a growth promoter for pigs. Globally, arsenic-based feed additives have been approved in many countries, including Japan and several Latin American nations. In 1993, China also permitted the use of arsenic compounds in pig and chicken feed. The Ministry of Agriculture’s 2001 guidelines allowed the use of organic arsenic preparations like arsenic acid and Roxarsone as feed additives.

Pig died of arsenic and attracted attention
Electric mosquito swatter is a kind of small household appliance products, mainly used to kill mosquitoes, flies, moths and other insects. It through the electronic high voltage technology, the use of 1850V high voltage to effectively destroy these pests, has the advantages of practical, convenient, no chemical pollution, safety and health, so it is widely welcomed, become the summer best-selling small household appliances products. The electric mosquito bat is usually composed of three layers of metal mesh, the outer metal mesh and the middle layer are not directly connected, and maintain a certain distance. When the switch is pressed, the direct current in the battery passes through the oscillation circuit and the boost circuit, eventually reaching a high voltage above 2000 volts. This design allows the mosquito to be waved through the electrostatic field and electrical grid discharge to destroy the insect, without causing harm to the human body.
The main advantages of electric mosquito swatting include:
Efficient pest control: can kill a variety of insects in a short time, including mosquitoes, flies and moths.
Safety and health: the use of high voltage electricity instead of chemical agents, to avoid chemical pollution, more environmental protection and safety.
Portable and convenient: compact size, easy to carry and use, suitable for home and outdoor use.
No chemical pollution: will not produce harmful chemicals, more friendly to the environment and human body.
The following points should be noted when using an electric mosquito swatter:
Avoid using in humid environment, so as not to affect its high pressure effect.
Keep the electric mosquito bat dry to avoid short circuit or damage caused by moisture.
Avoid using in flammable and explosive environments to prevent accidents.
Children should use under adult supervision to prevent accidental handling or risk of electric shock.
In short, with its high efficiency, safety and environmental protection characteristics, the electric mosquito has become an ideal choice for summer pest control.
